Not taking sides, just curious myself so lets see:
Of the top rated guys:
Lucky: Didn't live up to the hype, but played a lot, and was good in Cally's O.
Suh: You know that story. I'll venture to say he panned out...
Dillard: Drafted. Panned out.
Bowman: Was a JUCO. 2 years and drafted. Panned out.
Picou: Came in, redshirted as a fresh, then academically ineligible the next offseason. Transferred to a DII school and fell off the radar.
Brooks: Didn't have much for stats, but played in a decent amount of games, mostly special teams I believe.
Beck: Lost the back-up spot to Ganz, transferred to NC State, where he was outshined by Russell Wilson, and decided to graduate and quit football early.
Potter: A couple of all-B12 honorable mentions, I'd say he panned out.
And that pretty much covers the 4 star or higher guys. One reason this class was rated so highly, and is forgotten too often I think, is that it was a massive class of 31 guys.
